【火星技术前瞻】PEUGEOT宣传的最新巨NB自然进气发动机
240马力！标致1.5L MCE 5 VCRi发动机标致汽车近日宣布开发出一款全新的1.5升发动机，这款命为1.5L MCE 5 VCRi的发动机性能十分强大，最大功率达到惊人的220马力，最高扭矩达到420Nm，功率相当于普通的3.0升V6发动机，扭矩则达到普通V8发动机的水平。
标致1.5L MCE 5 VCRi发动机将在下周举行的日内瓦车展上首次发布，其将搭载在标致中级车407上。这款发动机在油耗方面依然有着优异的成绩，百公里油耗仅为6.7升，每公里二氧化碳排放量为158克。
标致表示，在今年年底将给1.5L MCE 5 VCRi发动机配备最新的GDI汽油直喷技术，到时这款发动机的功率将提升值270马力，最高扭矩也上升到460Nm，油耗则降低到每百公里6.0升，二氧化碳排放量有望降低到每公里140克的水平。 真的假的啊~ 虾米技术？gochinway50；）没看清。。 1# nExt.
1.5NA打死我都不信，我找到一些原版消息和标志新闻稿，关于NA还是增压，里面只字未提，感兴趣的TX看下文：
Peugeot has announced that it has developed a new 1.5L engine that develops 220 hp and 420 Nm of torque. The Peugeot 1.5L MCE 5 VCRi engine delivers as much power as a 3.0 liter V6 and the same amount of torque as you would get from a V8. The Peugeot 1.5L MCE 5 VCRi engine will be premiered at the Geneva Motor Show in March where it will be showcased in a Peugeot 407. The Peugeot 1.5L MCE 5 VCRi engine offers a fuel economy of 6.7 liters per 100 km and a 158 g/km CO2 emissions level.
Later this year the company says it will fit the new Peugeot 1.5L MCE 5 VCRi engine with GDI (gasoline direct injection) which will boost the power figure to 270 hp and the torque to 460 Nm while the fuel consumption will drop to 6.0 L / 100 km.
Peugeot Press Release:
The 79th International Motor Show in Geneva is kicking off a sluggish year for the automotive industry. Following on the heels of high oil prices, limited access to credit and the consequences of the financial crisis on purchasing power are today penalizing the automotive industry. The development of new gasoline engines will be essential to revive the industry since these engines will continue to represent over 80% of the market for the next 20 to 30 years.
These new engines must be able to boost the market and meet new regulations. Their production costs must remain affordable. In line with these objectives, MCE-5 technology already has a 12 year lead on what should be a fundamental stage in the development of IC engines: an "intelligent" variable compression ratio. VCRi heralds the renewal of car engine technology.
The first VCRi vehicle: a leap forward for automobiles
The Peugeot 407 type demonstration vehicle presented on the MCE-5 DEVELOPMENT stand
No 3000 in the Green Pavilion) is powered by a 1.5L MCE-5 VCRi engine that develops 220 hp, equal to that of a 3.0L V6 engine, and 420 Nm of torque as of 1500 rpm, comparable to that of a V8 gasoline engine. These results are achieved with a fuel consumption of 6.7 L / 100 km on the NEDC (158 g of CO2/km). This high performance 1.5L demonstration can of course be applied to lower engine capacities. These results are only intermediary ones obtained on an engine in development that is not equipped with GDI (gasoline direct injection) or the optimized combustion chambers expected in late 2009.
A 2010 version of MCE-5 VCRi engine will be equipped with GDI, optimized combustion chambers as well as the advanced management of engine temperature, of the cylinder head, pistons and exhaust manifold. The power and torque will respectively be ramped up to 270 hp and 460 Nm, while average consumption on the NDEC will drop under the 6.0 L / 100 km mark (less than 140 g of CO2/km). With this type of engine, reaching the target of 120 g of CO2/km seems realistic by 2012-2013 for high-performance vehicles, with a strong reduction in fuel consumption for the whole vehicle range.
A clear strategy from prototype to mass production
Many prototypes never reach mass production for
functional, economic or strategic reasons. As opposed to many other technologies that have been explored, the MCE-5 engine benefited as of the start of its development in 1997 from an approach resolutely focused on mass production. In 2009, twelve companies including major European Tier 1 automotive industry suppliers combined their talents to propose to carmakers a program intended to develop and manufacture the MCE-5 VCRi engine in the coming 6 to 8 years.
This proposal makes even more sense in the current economic, energy and environmental context, by addressing the main factor that will condition the automotive industry for the next 20 to 30 years: gasoline engine efficiency. 不会是类似大众的TSI吧？ 如果是真的，那就会有人把它装到206上了，呵呵~ 不会是类似大众的TSI吧？

就算是原装1.4tsi也只有170hp，240nm的功力.....so, 对这个号称1.5NA的机器极度怀疑中... 问题楼主贴的是1.5L啊~如果是TSI~再加上调教稍微不同~240P不难~~~问题在于如果是NA，那才惊人！ 的确有这个发动机，可变压缩比。 问题楼主贴的是1.5L啊~如果是TSI~再加上调教稍微不同~240P不难~~~问题在于如果是NA，那才惊人！

最高扭矩达到420Nm关键是这句
